Adjustable stroke, Double link motion and High precision
The NXT high precision and high speed model is equipped with a double link
motion mechanism. This mechanism allows a slide motion deceleration at
around the bottom dead point for an optimal stability of the ram
penetration and a drastic reduction of the vibrations inside the dies
during the cutting and forming operations. The crankshaft is
dynamically balanced. The frame material is casting iron FCD-50. The
slide is guided by 2 plungers and 4 posts for a perfect action against
eccentric load inside the dies. The change of the stroke length is
fully automatic. As for all Yamada presses, the NXT model is equipped
with an automatic oil temperature control (Heat & cool system)
which permits to guaranty an optimal stability of the slide penetration
from the first stamped parts at any constant speed or in acceleration.
The Yamada easy handling press control with its color touch screen
panel is very suitable for quick die changes with memorization of all
the press and feeder parameters (for a total of 1000 dies). A press
force monitoring is also included as standard equipment.
